To all 'whom it may concern:

Be it known that.vv l', JOHN A LLnNsoN, a. citizen of the United States, residing atSt. Paul, in the lcuuty of Ramsey and State ot Minnesota, have invented a new and use-` ful Improvement in PastryeBaking Machines, of which the :following .is a speci-v fication. n

My invention relates to improvements in molding machinesand more particularly to that class which is designed for the convenient. and expeditious production on a commercial scale of cones' or cups which may be composed of pastry or other material for containing ice-cream and other Jfood preparations or materials. l

Among further objects ol this invention is to introduce a machine which will mold and bake a plurality oi cones or cups evenly, quickly and effectively and to provide an apparatus from which the cones can be easily and quickly removed after they have been baked.

ln the accoim)anying` drawings forn'iing part. ot this specilication Figure l is a iront 'elevation oit my invention parts thereof being broken away; Fig. 2 is a side elevation a portion of the heater beingl shown; Fig. 3 is another side elevation showimgr the mold elements in reversed position; Fig'. 4 is a section of Fig. 1 taken on the line KNX the broken line position indicatingg` the core element ot' the molding members in superior' position; Fig. 5 is a view oi a detail; Fig. G is a side elevation ot the core mold element; Fig. 1' is a plan oithe core moldingjll clement;

Fig. 8 is a side elevation ci the matrix elcinent and Fig. t) is'a plan of said matrii"y element,

This invention comprises the following. main parts: matrix and core molds and B which cooperate together to mold and bake articles or manufacture such as pastry cups i'or holding.;` ice-cream, a trame (l oil-which said mold clen'ients are journaled to be ref versed with either the matrix or coreele` ments on top, turning .mechanism D for reversing the pair of mold elementsv` yel mechanism ll for holding the mold elements together during' the molding and baking` operation, an elevator l? whose function is to .raise the core mold element clear from thc matrix and turn it so that thel baked molded cups can be readily removed by the operator and the matrix relilled with batter ready to repeat an operation, and a heater G ampingl arranged to apply heat to t-he mold elements. These parts are so arranged that, the matrix element can be filled or partly `filled withbatter 'while the core element is clear and remote, therefrom, the core element can be lowered by the elevator into connection with the matrix and held in adypisted position with the ,batter filling the mold cavities by the clamping mechanism, and the moldvelements while connectedt'o-- gether can be reversed by the turning mechanismv to expose `|the oppositel sides ofl the mold to the heater to evenly and elfectively bake pastry cups in the mold. An organiza tion of elements of this character coperating together isadapted to speedily cast a large number of evenly baked pastry cups which are uniform and crisp and permits ofease in operation by unskilled labor. These features are obviously a reduce cost of production. -lrior devices do not accomplish these results as efficiently and inexpensively as by thishapparatus.

illold-The matrix mold comliirises a shell 2 having. a plurality ot' matrices or mold cavities 1 the walls ot which are of substantially even thickness so as to evenly con# duct heat to the inner wall of the mold cav-l ity for baking the molded articles therein. (ln the ends of the matrix mold are two half round gudgeons 8 and 4 the extremities of which are formed with transverse disks or bearing wheels 5 and G. The gudgeons 3 and 4 have transverse channels and the bearing wheel (l has upon its outside Ya pinion 8. The core member of ,the moldB is formed with a. plurality of depending cores 9 which as illustra-ted are conical and adapted to be inserted in the mold cavitiesl l tov form the molds for the articles to be cast,r

said cores land walls of the matrices being slightly spaced apart to produce n'iold cavities. The body or head 10 of the core member has the cores attached thereto by thread-` ed engagements 1.1 (see Fig.`4 and is formed with short' half round gu geons l2 4and 1 3 which complete substantially round gudgeons when eoaeting with the correspending\members 3 and 4 of the matrix member. The outer ends of the gudgeons 12 and 13 are formed withy angle extensions which produce guides 14 and 15 for the purposes to be hereinafter described. Qn the inner edges of these guides is a pair of anti-v friction rollers 16 and 17 which are jour- I naled upon bolts 18 secured in' the guides.v`l

s nism., for rever'singthe mold consists of a 4the mold can be lowered into placeor elevupright sides 28 and 29 each of which is adapted to receive the guides 14 and 15 on i the sides 28 and29 of the frame are open at 31 to admit the chains 22.

c f posed to the heater G below to'evenly 'bake g the moldedcups in the'mold cavities.

On the outer edges of the guides near their angles are pivot bolts 20 and 21 by which the ends of chains .22 formino' part o f tlie elevator to be hereinafter described,- are freely attached tohthecore member for raising -the latter.- The functions of the parts of the core and matrix members of the mold later.

'FrameA-The frame comprisesa bed 25 of suitable reinforced openwork construction having a pair of oppositely disposed journal bearings 26 and 27 in which the. gudgeons on the matrix and core members ofthe mold are journaled'. Thesefbearings are open on top so that the core .member of vated When desired and separated from the matrix. Secured upon the base is a pair of formed witha guide groove 30 which istlie 'coremember of a mold when it is raised. The guide grooves 30 after rising a. considera-ble dist-ance, turn into a horizontal' position and are so .shaped at their turns as to ladmit the guides and cause the core member. to turn from a horizontalinto a vertical position as illustrated by broken lines in Fi 4. y

'.l'lhe headsy of the bolts 2O upon the. core member have suiiicient-ly broad surfaces to form a slidingfcontact with the inner surfaces of the guide grooves 30 and thus hold the core member longitudinally. The upper portions of the sides of the guide .grooves in Extending forwardly at upwardly inclined angles are two journal supporting .arms 32 in the ends of which a transverse shaft 33 forming part of the elevator to be`hcreinafter described, is journaled. The lower portion ofthe bed is provided with a hood 34 in which is located a heater for the mold to be hereinafter described.` y

Turning mechansm.-`-'.lhe turning` mechatoothed segment 35 which isd ivoted upon a bolt 36 on one endof the be of the frame and has teethupon its perimeter which are adapted to mesh with the teeth ofthe pinion 8 ontheend of the gudgeon 4 of the matrix member of the mold.- This se ment carries an upwardly extending han le 37 which when invertical position causes the mold to assufne ,a .horizontal position as illustrated in Eig. 1f and' when tilted back into the position illustrated-'in Fig. 3 to reverse the mold with thematrixmember on top. In this manner .ei-ther sideof the mold canpbe ex'- A stop 544l o n the'matrix member of the mold: is adapted to impinge against vthesurtace of the bed of the frame in grooves and serves tionary in horizontal position when in either reversed position. 'This mechanism consists of a pair of dogs.38 one of which is placed on one side of the frame'and the other on the opposite sid'e to impinge upon the bearing wheels 5 and-G on the ends of the gudgeons 3 and 4 of the matrix member of the' mold. Each dog is pivotally mounted by a bolt 39 upon the bed in position.' so that its inner end 40 will press down upon one of the wheels 5 and 6. The dogs 38 are pressed into engagement With the wheels 5 and`6 on tliematrix member of the mold by a pairV of levers 41 each of which is pivotally mounted by a bolt 42 passing through lugs 43 on the bed with a short arm 44 pressing up against the outer extensions 45 of the dogs 38. The levers 41 are connected rigidly by a transverse ba'r 46 the inner edge of which midway between its ends is formed with a tooth 47 for engagement with teeth 48 on a.

ratchet bar 49 to hold the levers 41 station- 'or baked in the mold cavities when the maf trix member -is 1n uppermost position and at the same time the mold is free to be revolvedby the segment 35 and vreversed so as to expose either of its sides to th'e'heater.` The rack 459 is in the form of an upwardlyextending tooth bar havinv its'lower endpivoted in thelugs 50 on the ed by a'pin 51 and has an innery extension or angle l52 which is pressed up 'bya spring 53 soas to throw the rack with its teeth into spring engagement ,with the tooth 47. handle 54 is mounted upon the transverse support 46 so' that the levers 41 can be manipulated by hand and the dogs adjusted n on the clampin Wheels.

EZevaton-The e evator F whic is employed to raise the core mol element clear from the matrix and turn it into vertical Aposition so that the baked molded cups can be freely removed by the operator and the matrix refilled With batter ready to repeat an operation, comprises a pair of segments which are rigidly mounted upon the shaft 33. These segments have secured to the upper ends of their-perimeters 61 the upper ends of the chains 22 which are attached vary andthe dogs 38 tightly held upon the thereto'by means of bolts 62. 'When these segments are.swun up bythe shaft 33 the chains wrap upon t eir perimeters and raise superior tion. A handle 64 mounted upon one ot the segments 60 is employed for the purpose of turning said shaft and operating said elevator to raise or lower the core member of the mold. A counter balance weight (35 traveling over sheaves 66 illustrated dia grammatically in Fig. 1 is connected by a suitable bifurcated cable (37 with the lower ends of the perimeters of the segments (50, said weight acting to counter-act the weight of the core member and produce ease of operation of the elevator. he bifurcations of the cable wrap upon the 'erimeters of the segments G0 when the latter are turned.

I[eater.-The' heater G may be of any suitable construction or form. As illustrated it consists of a hydrocarbon burner 70 mounted within the hood 34 immediately belenT the mold. This b'urner is supplied with uel'from a suitable source not shown, through the supply pipe 71 which is regulated or shut oil by means of a valve '72.

Operationln operation the matrix member 1s filled or partly filled with batter and the core member lowered by the elevator into the matrix member. The cores nd their own seats in the batter in the matrices and produce molded' cups of even thickness because the core element is freely disposed and of suicient weight. After baking With the matrix member of the mold down clamping dogs 38 are adjusted over the perimeters of the wheels 5 and 6 and the levers ll1 applied to the dogs. The mold is then reversed to the action of the heat by turning it with its core member down into the position illustrated in Fig. 3 by tilting the handle 37 for- Ward. While in reversed position or While being reversed the dogs 38 serve to assist in holding the matrix member of the mold It Will be noted that the pairs of gudgeons 3 and 12 and 4: and 13 turn respectively in'the journals 26 and 27 While' the dogs 38 are holding the matrix member down and that by the adhesion of the batter to the molding elements and the gudgeons 12 and 13 of the core members fitting in the journals, the core member is prevented from slipping out of place when the mold members are being reversed. After the mold-is completely exposed to the heater as longr as As the core member rises in the,

desired, it is returned to its original osition. .The elevator is inally operate by means of the handle 64 and the core me ber raised into superior position., The cups adhere to the cones or cores on the core 470 member and project forward so that they can be easily and quickly removed by hand from the core member. Bosses 56 on the' ends of the matrix mold adjacent the gudgeons thereon serve as stops to guide and 75 hold the matrix mold longitudinally in the bed frame. The channels 7 in the gudgeons of the matrix mold serve to receive the chains of the elevator freely when the mold is reversed.
